Thanks Giorgio, certainly is. i found another paper by W. Engelhardt here http://redshift.vif.com/JournalFiles/V11NO2PDF/V11N2ENG.pdf - 'On the Relativistic Transformation of Electromagnetic Fields'. - 2004. he is a dude. tearing great holes in 'accepted' physics without breaking into a sweat. i ha...

A few more questions come to mind then. What is a ballpark density difference between core and cusp needed for things to work as Bussard envisions? A factor of 10, 100, 1000? The obvious follow on being if a factor of 2 is typical, what is the atypical extreme and is there a theoretical limit that ...

Oh Art, read on to the next sentence. I know that the confinement in the WB-7 is much, much better than ballistic. I also believe that the dominant energy flowthrough is in the electrons, not the ions. Glen Wurden (whom you probably know from LANL) has taken some fast framing pictures of the plasma...

He strongly implied your model didn't conform with what they're seeing His statement, directed to me, that "just because a piece of data is consistent with one model doesn't mean that it's inconsistent with another model", strongly implies that his data does not contradict my model. But g...

And I'm afraid your referenced post is the point where you lose me. Rather, more accurately, where I get lost. My physics isn't strong enough to follow through your argument and understand it properly. I'm afraid there probably isn't any way to dumb it down enough for someone at my level to grasp, ...

Sorry, I just don't find analyses that contradict what the experimenters are telling us very interesting. If Art wants to assume Rick hasn't actually seen WB confinement, fine, he's certainly entitled to do that given that nothing is published. I'm much more interested in analyses that would tend t...

Assuming good confinement requires that the cusp plasma contain predominantly electrons (and retaining for the first round the optimistic assumption of point cusps with radius rho_e), what is the maximum permissible density? If this value is not smaller than the density of ITER, for example, one mi...

If I'm not entirely lost, your saying the volume and density of the cusps is such that the potential there is impossibly high? Right. If I'm allowed a followup question, are there theoretically possible(even if improbable) values for the cusp volume and density relative to the core that aren't impo...

Sorry, I seem to keep asking stupid lay person questions. And Coulomb says, if electrons are in the cusp exhaust, then ions are there, too. Is that still true if the electrons in the core outnumber the ions by a sufficient amount? From my really limited understanding I don't see why the negative ch...

...Where the misconception is dwelling like a stubborn cough is the cusps. The cusps may be very small, but they are not small enough to allow a significant imbalance of ions and electrons. And yet some people seem to think that electrons can make an excursion out the cusps and back in again withou...

Apparently I used the term "non-neutral structure" without being sufficiently clear on what I meant. (It's implicit in the derivation - but that's a poor excuse.) What's the easiest way to say this? It's simplest if we only have protons and electrons. Quasi-neutral means the proton density...

Would you mind giving some numbers? ⋅ n_e ⋅ n_i ⋅ the geometry of the structure (smallest dimension, and whether it is more spherical, cylindrical, or slab shaped) ⋅ the potential difference within the structure ⋅ WB6 dimensions, 0.1T ⋅ sp...

For a sphere with radius R and a uniform charge density rho , the potential difference between the center of the sphere and infinity is Phi = 0.5*(rho/epsilon_0)*R^2 Take Phi and rho as given, and solve for R: R = sqrt( 2*(e*Phi) / (rho*e/epsilon_0) ) What's the lowest density that could produce ma...

Are you saying that one can find in those pictures a structure where the ratio of ion to electron density differs significantly from unity, and where the density, potential difference, and size differ significantly from the relationship I gave? Basically, yes. The model/picture there satisfy the Co...
